DUMB-WAITER FOR BOOTS AND THE LIKE.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed March 4. 1907. Serial No. 36014101 T 0 all whom it mayconcern:

Be it known that I, HEINRIGH ALFRED BRUGGER, a citizen of the Republicof Swit zerland, residing at Radolfzell, Germany, have invented certainnew and useful Improvements in Dumb-VVaiters for Boots and the Like; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters or figures of referencemarked thereon, which form a part of this s ecification.

The occupants 0 bedrooms, especially in hotels and the like, often findit inconvenient during dressing or undressin to put their shoes at nightoutside the bec room door, in the passage, or to remove the same fromthe passage into the room in the morning, inasmuch as they are obligedto open the door in a partially undressed condition. Moreover it isinconvenient to handle dirty shoes until clean collars and other easilysoiled articles of clothing have been put on or taken off.

The subject of the present application is a dumb-waiter, that is adevice for the delivery of shoes and other articles from a room into anadjacent s ace and back again, whereby the above-inc icatedinconveniences are obviated.

According to this invention there is provided in an opening in the walldividing the two spaces a transporting mechanism adapted for thereception of the article in question. This mechanism can be pushed fromeach space towards the other space and is always accessible from thatspace to which it has been pushed; and the opening in the wall is closein each terminal positlon of the said mechanism.

The apparatus is illustrated in the accompanying drawing as follows:Figure 1 shows the apparatus in elevation, and partial section. Fig. 2shows the same in plan view, partially broken off. Figs. 3 and 4 showthe apparatus in front elevation, with parts in two different positions.

The apparatus consists of a box 1, open at both ends and on the top,built into the opening in the party wall between two adjacent spaces. Inthe side walls 2 and 3 of the said box is secured a shaft 6 having flaps4 and 5 fixed at a right angle to one another. Upon the shaft 6, outsidethe box 1, is secured the angle-lever 7, by means of the projecting arm8 of which from one space, for instance a bedroom, the shaft 6 can beturned and thereby the wings 4, 5 alternately brought into the verticalposition, whereby the box 1 is divided into two chambers 9, 10. The arm11 of the lever 7 is connected with the pusher rod 12 by means of theslotted piece 13. The pusher rod 12 is supported in eyes 14 on the sidewall 3 of the box 1, and is limited on its inward motion by the stop 15on the box 1. The front end of the pusher rod, provided with a handle,projects into the other space, in this case into the passage. The shaft6 can thus be turned from the bedroom by means of the arm 8 and from thepassage by means of the pusher rod 12. To the wings 4, 5 is secured anarc 16, in the slot 17 of which engages the pin 18 of a sliding tray 19.When the shaft 6 is turned, the arc 16 forces the tray 19 by means ofthe pin 18 to and fro between the chambers 9 and 10. The tray. has a lowfront Wall 20 and is guided in grooves 21 on the side Walls 2, 3 of thebox.

The operation of the apparatus is as follows. Assume that in theposition illustrated in full lines in Fig. 1 the objects to be moved,for instance boots, stand in the chamber 9 upon the tray 19, where theservant after having cleaned them has placed them. The chamber 9 isseparated from the chamber 10, communicating with the bedroom by thewing 4, which at the same time closes the opening in the wall. Theinmate, in order to obtain the boots, raises the arm 8 into the positionindicated in dotted lines. This brings the wing 4 into a horizontal andthe Wing 5 into a vertical position, while the tray 19 and pusher rod 12assume the positions indicated in dotted lines. The chambers 9, 10 arenow separated from one another by means of the wing 5 and the opening inthe party wall is closed thereby. The occupant now has the boots insidehis chamber; he can, instead of them, place upon the tray 19 any otherobjects, in order to de liver the same, by moving back the arm 8 intothe position indicated in full lines, to the chamber 9 and thus to thepassage. The servant can recognize by the in or out position of thepusher rod 12, whether the guest requires attendance. If the guest hasplaced anything upon the tray 19, but has omitted to deliver it into theproper position by horizontal adjustment of the lever 8, the servant, bydrawing out the pusher rod 12 can himself move the tray 19 and therebywithdraw the objects lying upon it from the room. He can deliver themagain by pushing in the pusher rod 12.

By means of the above-described device, therefore, boots, shoes, orother objects, can be mechanically conveyed from a room into a passageor other-adjacent space and be again delivered from the same back intothe room, without necessitating the opening of the room-door for thepurpose, whereby the person in the room is saved from inconvenience.

Delivery devices of this kind are also capable of application withadvantage in hospitals, in order to provide for delivery of articlesfrom and to the sickchamber with as little noise as possible and inorder to revent the frequently injurious drafts caused y opening thedoors.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed I declare thatwhat I claim is:

1. A dumbwaiter, comprising in combination an open ended box adapted tobe fixed in an opening in a partition, a tray slidable in the box, apair of flaps making an angle with one another and mounted to revolveabout the apex of the angle, means to revolve the flaps, and mechanismto simultaneously move the tray when the flaps are revolved.

2. A dumb-waiter, comprising in combination an open ended box adapted tobe fixed in an opening in a partition, a tray slidable in the box, apair of flaps in angular relation and mounted on an axis in the box,means on each side of the box to actuate the flaps to close the opening,and a slidable connection between the tray and flaps whereby said traywill be caused to slide in the box between the flaps during thepositioning of the latter to close the opening.

3. A dumb-waiter, comprising in combination, an open-ended casingadapted to be fixed in a perforated partition; a waiter sliding therein;two closing devices, each closing the aperture in one end-position ofthe waiter and at right angles to each other and means at each side ofthe partition for revolving the said closing devices, said twoactuating-means being coupled, whereby as one device exposes theaperture the other device closes the latter; substantially as described.

4. A dumb-waiter, comprising in combination, an open ended casingadapted to be fixed in a perforated partition; a transverse rockingshaft mounted in the casing; a waiter sliding in the latter below theshaft; waiter reciprocating means actu ated by the shaft; two deviceseach closing the aperture in one end-position of the waiter; and meansat each side of the aperture for actuating the said closing-devices,said two actuating-means being coupled, whereby as one device exposesthe aperture the other device closes the latter; substantially asdescribed.
